    Just saying Hi and give a little info about me and I have a question...

    Im James! Im 20 years old and I'm from Ontario Canada and I drive a 1993 Mazda Miata (Black on Tan).

    Here is my question. I am going to be starting on a "CarPuter" soon as the cars back from paint and I was wondering how much heat can a laptop take? By heat I mean outside temperature. I was going to mount the laptop under the driver seat but I have doubts because during the summer the car gets quite hot inside while the car is just sitting. I searched the forums and came up with nothing but information on processor temperatures. If there is another thread please point me to it! Thanks!

    Welcom to the insanity. You'll be fine. Ambient interior temperatures are nothing compared to the temps a CPU can put up with. Just make sure you have decent cooling and dont use some monster heat generating cpu.

      Alrighty! Sounds good! Thanks for the quick response. And by "Welcome to the insanity" I know what you mean! I haven't even started and its already driving me nuts!

        arg! i had a nice long message typed up for but this damn dialup at work craped out when i hit submit. *sigh* i hate dialup at work.

        anyway, what i was saying was:
        The electronics might be ok. But the plastic could suffer damage on a really hot day if the plastics are not that good in quality. Toshiba satelites comes to mind (by experience) .

        After doing some quick research on google about car temperatures in the summer, It appears to be unanimous that the inner temp of cars rises about 40F in the first 20 min. So if its 90F and you leave your car to go to the store or whatever, 20 min later your car's inner temp may be at 130F. If your car is in direct sunlight, it could be higher.

        CPU's usually shut down by protection at about 140F (60c.) Check your bios settings to see what your cpu temp protection is set at (just done change it!).

        Of course your car won't be at that high of a temperature all the time. as soon as your open your car it starts cooling.

        There are members here who have laptops as carputers.
        Im sure they will give their opinion of the thread catches their eye.

        btw, try to keep your subject lines descriptive. I personally tend to ignore poorly worded or non descriptive subject lines. Keeping that in mind will get the attention, help and answers needed.

        and... Welcome!

          If you are from Ontario Canada I would be more concerned with the effects of cold on both your CPU and your display. Laptop is the obvious choice here since you can simply remove the unit during the cold months. The display will be a little more tricky if you go with an integrated solution. This is the main reason (other than theft) that I decided to use a gooseneck and quick disconnects for my touch screen.

              The CPU isn't really your main problem when considering operating temps. Double check the operating temperatures of your laptop hard drive. Most drives have a pretty high operating temp ceiling(in my case 60 degrees Celcius), but don't like to operate if too cold(in my case below 5 degrees Celcius). You'll be fine once the drives warm up a bit, but you may receive some data read errors until then.

                  Check the FAQ Emporium for a thread on "climate extremes" and their effect on car PC's.

                    ah yeah that is true... not to change the subject from hot to cold but, I have 2 notebook hard drives and one does not boot if it gets below 30f ~0c.

                    Im quite impressed with the Hitachi Travelstar model IC25N040ATCS04-0. That drive has spun up with no issues even at around 14F (-10c) while the other drive (not sure of model right off hand) wont spin up untill its warm. Just another thing to consider.

                    I agree on being more worried about the hard drive than the CPU. After all, that is where your data will be stored and if that fails; I hope you have a backup. I feel that everyone here knows to treat hard drives as a disposable item that is going to break eventually. To me its quite a thrill to see my drive still work after every trip But yeah, im pleased with my Hitachi drive. Definetly going to buy another just like it when the time comes.
